Proline Promag 55 FOUNDATION Fieldbus Safety instructions
Endress+Hauser 5
1 Safety instructions
1.1 Designated use
The measuring device described in this Operating Manual is to be used only for measuring the flow
rate of conductive fluids in closed pipes.
All fluids (including demineralized water) can be metered, provided they have a minimum
conductivity of 5 μS/cm, for example:
• Acids, alkalis, pastes, paps, pulps, black liquor, green liquor
• Drinking water, wastewater, sewage sludge,
• Milk, beer, wine, mineral water, yoghurt, molasses, fruit mash,
• Cement slurry, ore slurry (containing sand or stone), mud, silt
Incorrect use or use other than that designated may result in the operational safety of the measuring
devices being suspended. The manufacturer accepts no liability for damages resulting from this.
1.2 Installation, commissioning and operation
Note the following points:
• Installation, connection to the electricity supply, commissioning and maintenance of the device
must be carried out by trained, qualified specialists authorized to perform such work by the
facility's owner-operator. The specialist must have read and understood these Operating
Instructions and must follow the instructions they contain.
• The device must be operated only by persons authorized and trained by the system operator. Strict
compliance with the instructions in the Operating Instructions is mandatory.
• Endress+Hauser is willing to assist in clarifying the chemical resistance properties of parts wetted
by special fluids, including fluids used for cleaning. However, small changes in temperature,
concentration or the degree of contamination in the process can result in changes to the chemical
resistance properties. For this reason, Endress+Hauser does not accept any responsibility with
regard to the corrosion resistance of materials wetted by fluids in a specific application. The user
is responsible for the choice of wetted materials with regard to their in-process resistance to
corrosion.
• If welding work is performed on the piping system, do not ground the welding appliance through
the flowmeter.
• The installer must ensure that the measuring system is correctly wired in accordance with the
wiring diagrams. The transmitter must be grounded, except in cases where special protective
measures have been taken (e.g. galvanically isolated power supply SELV
or PELV).
• Always note the regulations applicable in your country to the operation, maintenance and repair
of electrical devices. Special instructions relating to the device can be found in the relevant
sections of the documentation.
• The Promag 55 flow measuring device can also measure extremely abrasive fluids, e.g. ore slurry,
cement etc. To protect the measuring tube lining from excessive abrasion, the use of additional
liner protection plates is recommended in such cases.
1.3 Operational safety
Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of these Operating Instructions. Strict compliance with
the installation instructions and ratings as stated in this supplementary documentation is
mandatory. Depending on the approval and certification agency, the relevant symbol is depicted
on the front page of the supplementary documentation on Ex ratings (e.g. 0Europe, 2USA,
1Canada).

Safety instructions Proline Promag 55 FOUNDATION Fieldbus
6Endress+Hauser
• The measuring device meets the general safety requirements according to EN 61010-1 and the
EMC requirements according to IEC/EN 61326 in addition to the NAMUR recommendations
NE 21, NE 43 and NE 53.
• Depending on the application, the seals of the process connections of the Promag H sensor require
periodic replacement.
• Due to the performance rate in the electronic components, the external housing surfaces are
heated to a maximum of 10 K. When conducting hot media through the measuring tube, the
surface temperature of the housing increases. Particularly in the case of the sensor, temperatures
close to the fluid temperature must be anticipated. In the event of elevated fluid temperatures,
please ensure that fire protection is in place.
• The manufacturer reserves the right to modify technical data without prior notice. Your
Endress+Hauser distributor will supply you with current information and updates to these
Operating Instructions.
1.4 Return
• Do not return a measuring device if you are not absolutely certain that all traces of hazardous
substances have been removed, e.g. substances which have penetrated crevices or diffused
through plastic.
• Costs incurred for waste disposal and injury (burns, etc.) due to inadequate cleaning will be
charged to the owner-operator.

3 Installation
3.1 Incoming acceptance, transport and storage
3.1.1 Incoming acceptance
On receipt of the goods, check the following points:
• Check the packaging and the contents for damage.
• Check the shipment, make sure nothing is missing and that the scope of supply matches your
order.
3.1.2 Transport
The following instructions apply to unpacking and to transporting the device to its final location:
• Transport the devices in the containers in which they are delivered.
• Do not remove the protection plates or caps on the process connections until you are ready to
install the device. This is particularly important in the case of sensors with PTFE linings.
Special notes on flanged devices
"Caution!
• The wooden covers mounted on the flanges before the device leaves the factory protect the linings
on the flanges during storage and transportation. Do not remove these protection plates until
immediately before the device is installed in the pipe.
• Do not lift flanged devices by the transmitter housing or, in the case of the remote version, by the
connection housing.
Transporting flanged devices (DN ≤300) 12"
Use webbing slings slung round the two process connections. Do not use chains, as they could
damage the housing.
#Warning!
Risk of injury if the measuring device slips. The center of gravity of the assembled measuring device
might be higher than the points around which the slings are slung.
At all times, therefore, make sure that the device does not unexpectedly turn around its axis or slip.

Transporting flanged devices DN > 300 (12")
Use only the metal eyes on the flanges for transporting the device, lifting it and positioning the
sensor in the piping.
"Caution!
Do not attempt to lift the sensor with the tines of a fork-lift truck beneath the metal casing. This
would buckle the casing and damage the internal magnetic coils.
a0004295
Fig. 5: Transporting sensors with DN > 300 (12")
3.1.3 Storage
Note the following points:
• Pack the measuring device in such a way as to protect it reliably against impact for storage (and
transportation). The original packaging provides optimum protection.
• The storage temperature corresponds to the operating temperature range of the measuring
transmitter and the appropriate measuring sensors →ä104.
• The measuring device must be protected against direct sunlight during storage in order to avoid
unacceptably high surface temperatures.
• Choose a storage location where moisture does not collect in the measuring device. This will help
prevent fungus and bacteria infestation which can damage the lining.
• Do not remove the protection plates or caps on the process connections until you are ready to
install the device. This is particularly important in the case of sensors with PTFE linings.

3.2 Installation conditions
3.2.1 Dimensions
All the dimensions and lengths of the sensor and transmitter are provided in the separate
documentation "Technical Information".
3.2.2 Mounting location
The accumulation of air or gas bubbles in the measuring tube could result in an increase in
measuring errors.
Avoid the following locations:
• At the highest point of a pipeline. Risk of air accumulating.
• Directly upstream from a free pipe outlet in a vertical pipeline.

Fig. 6: Mounting location
Installing pumps
Do not install the sensor on the intake side of a pump. This precaution is to avoid low pressure and
the consequent risk of damage to the lining of the measuring tube. Information on the lining's
resistance to partial vacuum →ä107.
It might be necessary to install pulse dampers in systems incorporating reciprocating, diaphragm or
peristaltic pumps. Information on the measuring system's resistance to vibration and shock
→ä104.

Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty Pipe Detection
function offers additional protection by detecting empty or partially filled pipes →ä75.
"Caution!
Risk of solids accumulating. Do not install the sensor at the lowest point in the drain. It is advisable
to install a cleaning valve.
A0011901
Fig. 8: Installation in partially filled pipe
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes longer than 5 meters (16 ft).
This precaution is to avoid low pressure and the consequent risk of damage to the lining of the
measuring tube. This measure also prevents the system losing prime, which could cause air
inclusions.
Information on the lining's resistance to partial vacuum →ä107.

3.2.3 Orientation
An optimum orientation position helps avoid gas and air accumulations and deposits in the
measuring tube. Promag, nevertheless, supplies a range of functions and accessories for correct
measuring of problematic fluids:
• Electrode Cleaning Circuitry (ECC) to prevent electrically conductive deposits in the measuring
tube, e.g. for fluids causing buildup (see "Description of Device Functions" manual).
• Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes or in the case
of degassing fluids →ä75.
Vertical orientation
A vertical orientation is ideal in the following cases:
• For self-emptying piping systems and when using empty pipe detection.
• For sludge containing sand or stones and where the solids cause sedimentation.
A0011903
Fig. 10: Vertical orientation
Horizontal orientation
The measuring electrode plane should be horizontal. This prevents brief insulation of the two
electrodes by entrained air bubbles.
"Caution!
Empty Pipe Detection functions correctly with the measuring device installed horizontally only
when the transmitter housing is facing upward (see diagram). Otherwise there is no guarantee that
Empty Pipe Detection will respond if the measuring tube is only partially filled.

3.2.4 Inlet and outlet runs
If possible, install the sensor in a location upstream of fittings such as valves, T-pieces, elbows, etc.
Compliance with the following requirements for the inlet and outlet runs is necessary in order to
ensure measuring accuracy.
• Inlet run ≥5 × DN
•Outletrun≥2 × DN
A0011905

3.2.5 Vibrations
Secure and fix both the piping and the sensor if the vibrations are severe.
"Caution!
It is advisable to install sensor and transmitter separately if vibration is excessively severe.
Information on the permitted resistance to vibration and shock →ä104.

3.2.6 Foundations, supports
If the nominal diameter is DN ≥350 (14"), mount the sensor on a foundation of adequate load-
bearing strength.
"Caution!
Risk of damage.
Do not support the weight of the sensor on the metal casing: the casing would buckle and damage
the internal magnetic coils.
a0003209
Fig. 14: Correct support for large nominal diameters (DN ≥350/14")
3.2.7 Adapters
Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor in larger-
diameter pipes. The resultant increase in the rate of flow improves measuring accuracy with very
slow-moving fluids.
The nomogram shown here can be used to calculate the pressure loss caused by cross-section
reduction.
!Note!
The nomogram only applies to liquids of viscosity similar to water.
1. Calculate the ratio of the diameters d/D.
2. From the nomogram, read off the pressure loss as a function of fluid velocity (downstream from
the reduction) and the d/D ratio.

3.2.8 Nominal diameter and flow rate
The diameter of the pipe and the flow rate determine the nominal diameter of the sensor. The
optimum flow velocity is between 2 and 3 m/s (6 to 10 ft/s). The flow velocity (v), moreover, has
to be matched to the physical properties of the fluid:
• v < 2 m/s (<6 ft/s): for abrasive fluids where solids do not cause sedimentation (e.g. lime milk)
• v > 2 m/s (>6 ft/s): for fluids producing buildup (e.g. wastewater sludge)
• v > 2 m/s (>6 ft/s): for abrasive sludge with a high sand or stone content and where the solids
easily cause sedimentation (e.g. ore slurry)
!Note!
Flow velocity can be increased, if necessary, by reducing the nominal diameter of the sensor through
the use of adapters →ä17.
